We encourage contributors to add code to extend our supported sensors. Please review existing issues to see which sensors and types are currently being worked on. We'll eventually build a list of compatible sensors.
Using I2C, you can "daisy chain" multiple sets of I2C sensors together, or use multiple devices with balenaSense to aggregate data. See our official project guide's section on data aggregation to learn more about this and the sensor block.
While the stock/default dashboard is a helpful way to start, you'll probably want to customize your own visualizations at some point. Please follow this subsection of our project guide for dashboard customization.
If you have a favorite way to customize your balenaSense dashboard, feel free to contribute to this documentation.
